SLICING-MACHINE.

To all 'whom it mayiconcern: 'l

Be it known that I, EDWARD F. S M 1TH, a citizen of the 'United States, residmg at Rochester, in the county of Monroe and' State of New York, have invented certain new and4 useful Improvements in Shcing- Machines, of which the following is a speciication, reference being had vtherein to the accompanying drawing. n

My invention relates to improvements-in slicing machines.

An Aobject of my' invention is to provide a slicer of the character in which the guard .or gage for varying the thickness of the 'clamped upon a table or shelf. Fig. 2 is an end view looking toward the'right, Fig. 1. Fig. 3 1s a longitudinalsectional view taken on the line of the knife shaft, showing the gage plate adj-usting means'. Fig. 4 is a side view of the knife showing the meat support in dotted lines and showing the position of the knife as it starts to cut., This view shows in dotted lines the common form Aas of knife and lapproximately when it will start to cut. Fig. 5 is a view similar to Fig. 4, only showing the knife in its shearing cutting position. 1

Referring now to the drawings, .1 represents the meat support which is provided at one end by the'legsi2 and 3, and at the opposite end by the lug 4. The lug 4 is pro-- vided with a horizontal stud 5, upon which is pivotally mounted the U-shaped clamp 6, which is adapted to' straddle a table or shelf 7, and the lower endfof said clamp is provided with a thumb screw 8, by means .of which the machine may be readily clamped to the table-.-`=.'1he, legs 2 and 3 have their Specification of Letters Patent.

at the same time bring the shearing surface 1l 1n such a position in respect to the knife that a 'better shear cut is made. Within vthe meat support is a feeder plate 11, which has a rearwardly and downwardly extending arm 12 carried by its rear edge and through which passes the rod 13whereby the feeder plate may be readily moved longitudinally within the meat support and at. the same-time allowing the same to be swung upwardly so that the meat can be readily inserted in the support. The feeder plate, as v.heretofore stated, slides inA the meat support and is adapted to slide freely therein by means of the handle 112 and' forces the meat forward toward the knife,

`as will be later more fully described.

The upper side wall 14 of the oblique meat support 1 is provided with an elon gated shaft bearing 15, which is preferably bolted thereto by means of bolts 16. Mounted in said bearings is a shaft 17, which has a collar 18 on its outer end -which bears against the end of the bearing. The outer end of the shaft is provided with a screw threaded opening 19 into which is screwed the machine screw 20, the head of which bears against a washer 21, said washer holding the collar 18 against the end of the bearing` and'wheleby the shaft is held against longitudinal movement to the right, as shown in` Fig. 3.

Surrounding the shaft adjacent the opposite end of the bearing 15 is a casting 22, which is provided with an enlarged hub 23, and passing through said hub is a set-screw 24, which engages the shaft 17 and firmly locks the same upon the shaft. Screwed to the inner face of the casting 22, by means of the screws 25, is the blade 26, which is of the shape shown, and which will be hereinafter more fully described'. The blade as shown'is of a crescent form and has a spiralshaped inner edge, whereby the knife has a side shearing action' on the meat from the. time it starts to cut. j

The outer end 0f the shaft 17 is screwthreaded, as indicated at 27 and screwed thereon is a hand-wheel 28 having roughened outer edges whereby it may be readily screwed inwardly or outwardly on the shaft. The said hand-wheel 'has a hub portion 29 provided with a peripheral groove 30, into which extends the lug 31, carried by the plate 32. The platel 32 is secured upon the orgage-plate 36.

outer periphery of the hub 33, of the guard This hub, as shown, is free to move longitudinally upon the shaft and by the turning of the hand wheel the gage plate is moved in or out. This hub is provided with the hollow portion 35, which is adapted to extend over ,the hub 23 and carries the gage plate proper 36. rlhis plate is of a circular form having an opening 37 therein the same shape asthat of the blade, only slightly larger so that there is a clearance space entirely surrounding the blade. The hollow portion of the hub 35 is provided with a notch 38 through which the set screw 24 extends and whereby the knife is adjusted on the shaft to or from the shearing surface ll, of the meat support. In order to hold the gage plate against rotation onl the shaft 17, so that it will rotate with the knife-shaft, l provide a set-screw which enters a longitudinal slot 41, in the Screw-threaded portion of the shaft 17, and

' also holds the gage platewhile moving from A that adjustment.

I'llhe knife and casting being held by setscrew 24, it will be readily seen that the ad? justment of the gage-plate 34 in or out by the hand-wheel 28 will vary the thickness of the slice.

Carried by the leg 2 is a guard plate 42 which isy 'ofa curved form and secured to the leg by means A of the bolt 43. Bolted to the lower' edge of the curved guard-plate 42 is a lateral curved plate 44, all of which lis adapted to protect the knife and gage-plate as will be readily seen from the drawings.

rThe knife 26, as shown in Figs. 2, 4 and 5 is of an elongated curved form mounted at its inner end upon the shaft 17 a The outer cutting edge of the knife starts from the point 46, which is on the inside of the shaft 17 and extends spirally outwardly the'spiral gradually increasing toward the outer end for causing a shearing action, as will be hereinafter more fully described.

The meat support l is set atan angle and the shaft 17 carrying the knife 26 is so located in respect thereto that as the gageplate 36 carrying the knife 26 is revolved by means of the handle 42', the knife starts across 'the meat support and has a shearing action from the time of starting to cut, as

clearly shown in Fig'.- 4 of the drawings. 'lhis specific form of knife and its location in lrespect to the meat support causes the knifeto start to cut across the support at the lower end thereof so that a shearing cut is obtained and at the same timethe knife is traveling downwardly, as shown in Fig. 5.

Fig. 4 of the drawings, shows the cutting edge of the old form of knife in dotted lines, the cutting portion starting at the point designated A,iand thus it will be seen that A meat slicer, comprising a meat support,

a rotary shaft carried by said support, a knife mounted on said shaft yand having an outwardly extending hub, aset screw pass-- ing through the hub and securing the knife on the shaft, a gage plate longitudinally adjustable on the shaft, a handle carried by the gage-plate, a hollow hub mounted upon the shaft and adapted' to receive the knife y hub and having a cut-away portion to eX- pose the set-screw, a set screw carried by the hub and entering a longitudinal slot in 'the shaft to hold the same against rotation .relatively to the shaft,but allowing it to freely slide thereon, 'a hand wheel screwed upon the outer end of the shaft and having a peripheral groove, and a member rigidly carried by the hub of the gage-plate and having'a lateral lug entering the peripheral groove substantially as described.

In testimony whereof ll hereunto aix my signature in the presence of two witnesses. EDWARD F. SMITH.
